It's beautiful sacrilege, putting a built Cummins 12V turbodiesel into a 1968 Corvette. Ryan Lusk of Iowa-based Low Budget Diesel Performance has done just that, and he's decided to take the car drag racing. Ryan is a great American hero.
Of all the places we hear about crazy contraptions, our absolute favorite and unquestionably least likely source is a subscription-only newspaper-style printed publication called Farm Show. It's a fantastic collection of the most clever, ridiculous, scary and cool creations to come out of farmer's garages. We picked up a copy back home on the farm while recovering from taking down unnatural amounts of turkey and stuffing and all the Thanksgiving trimmings, and guess what we found. Amidst the loader scoops made from cut-in-half LP tanks, home brew automatic silage choppers, and articulated tractors made out of two junked Chevy pickups welded together, a 1968 Corvette powered by a 12 valve Cummins. The post-meal nap was immediately postponed.
The car is the creation of Ryan Lusk, a diesel mechanic in Iowa with a side business called Low Budget Diesel Performance where he converts vehicles by installing diesel engines for better fuel economy and performance. This Corvette came to him as a rear end smash up. Instead of replacing everything with factory parts, Ryan decided to make a drag racer out of it. We'll let him explain:
When I purchased the car it was wrecked in the rear pretty severly. Instead of rebuilding the car with over priced Corvette parts, I opted to back half the rear of the frame and tub it. It now has a 4-link coil over rear suspension with a ford 9". I had a 396 BBC with a tunnel ram and dual quads in it that made over 550hp in the beginning. I also had some sweet chrome side pipe headers as well. It was coming along well
Amongst the progress of the diesel conversions we were completing, the Vette sat for a long time. One day my Dad made the comment that I should just ditch the gas guzzling BBC and throw a Cummins in it. I was like heck no, I'm not going to ruin the Vette! Well the more I thought about it, the more I wanted to do this. I started the project in March of 2008. We will be at Beechbend Racetrack in Bowling Green Kentucky for the NHRDA Diesel Nationals. Weight of car with driver: 3620

We think it safe to say this is the best possible thing you could ever do with a previously-crashed plastic fantastic. There's so much awesome piled into this car it's practically incomprehensible. Actually, hold that thought, you haven't seen the car running. Check out the three videos below.

We're going to parrot the words of the drag racing announcer.... "Oh my GOD!?" If we may humbly make one suggestion to Mr. Lusk, we think it needs a constant stream of the Nuge piped to exterior speakers to properly serenade that majestic turbodiesel note. Nothing else so uncontrollable and unpredictably violent could possibly do the job.
